A colourful departure for the iconic Swiss bottle maker, these new models from Sigg have a 750ml capacity and fill a welcome hole for those for whom the famous aluminium bottles are a bit industrial-feeling. BPA-free, recycled and recyclable, yet forged with the quality you’d expect from Sigg that makes the latter highly unlikely, the Viva also features a double lid that makes it easier to fill and filter. Perhaps the most significant, unspoken virtue over Sigg’s most famous fare is you can actually see how much water you’ve got left!
